SPECIFICATION forming part of Letters Patent No. 593,909, dated November16, 1.897.

Application filed April 2v2, 189.7.

To all whom t may concern:

Be it known that I, ALFRED F. SMITH, of Las Vegas, in the county of SanMiguel and Territory of New Mexico, have invented a new and ImprovedWindow-Sash, of which the following is a full, clear, and exactdescription.

-This invention is an improvement in window-sashes by which the sashesmay be readily removed from the frame without withdrawing screws ornails or other permanent fastening devices.

This specification is the disclosure of one form of my invention, whilethe claims dene the actual scope of the conception.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the gures.

Figure 1 is a perspective view of the invention complete. Fig. 2 is afragmentary perspective view showing the sashes removed. Fig. 3 is aperspective view of one of the sashes.. Fig. 4 is a sectional viewshowing the lock between the sash and the cleats. Fig. 5 is a sectionalview showingt-he catch for the cleats. Fig. 6 is a sectional view takenhorizontally through one of the locks shown in Fig. 4, and Figs; 7 and 8are detail views of forms' of slides for the sash.

The frame 10 of the window has three vertical beads 1l, secured on eachinner face and forming in each side of the frame two verti. calguideways. Sliding in each guideway is a cleat 12. l of the beadsll ateach side of the sash have recesses 13 formed therein and surrounded bywear-plates 14, oriced to register with the recesses 13. Each cleat 12has a recess 15, covered vby a plate 16 andcarrying a spring-pressed andcam-shaped bolt 17. The bolts 17 are respectively adapted to lock` withthe plates 14 and recesses 13, whereby to hold the cleats 12 at thelimit of their upward movement. The bolts 17 may be disengaged from theplates 14 by applying to the cleats 12 such force as will overcome thepressure of the springactuating the. bolt 17.

The complete window has four cleats 12, two being normally in rigidconnection with each sash. Each sash 18 has (according to Figs. l to 6)a plate 19, the edges of which are bent to form yflanges respectivelyengag- The upper front portions of twoj Serial No. 633,355. (No model.)

ing the overhanging edges on the plates 20, which are respectivelycarried by the cleats 12. The plates 2O are rigidly secured to thecleats 12 and terminate slightly above the lower ends of the cleats 12.Each'plate 2O has an opening 2l, with which the lock-bolts 22 arerespectively adapted to engage. Each sash has two lock-bolts,respectively slidable in casings 23, sunken in the sashes and having twolimbs 24 and 25, the former of which projects inward at its end, so asto partly inclose the respective tumblers 26. The hollow trunnions ofthe tumblers 26 are respectively revolubly mounted within the sides ofthe cas'ings 23 and project through one side of the sashes, Vso that akey 27 (shown in Fig. 6)'may be inserted within the trunnions of thetumblers 26 to operate the same in a manner indicated by dotted lines inFig. 4, so as to throw the bolts 22. Figs. 1 and 3 show the trunnions ofthe tumblers 26 projecting to the outer side of the window-sash.

^ Normally the sashes are rigidly connected by the bolts 22 with theirrespective cleats 12, so that the sashes and cleats slide in unisonasthe sashes are adjusted in the ordinary manner of operation. IfY it bedesired to hold both the sashes in an elevated position, the sashes aremoved so that the bolts 17 will engage with the plates 14 and recesses13. If it be desired to remove the sashes from the window-frame for thepurpose of cleaning, repairing, or otherwise treating the window-sashes,the sashes should be moved to the limit of their upward movement, andthe tumblers 26 should be operated to throw the bolts 22 out ofengagement with the plates 20. Y The sashes will now be disconnectedfrom the cleats, andl the sashes may be permitted to vdrop until thesashes run 0E from the plates 2O and are thus completely separated fromthe window-frame. The application of the sashes is effected by a merereversal of the above operation.

Figs. 7 and 8 show substitutes for the parts 19 and 2O in Figs. 1 to 6.Fig. 7shows a channeled plate 28, two of which are carried von each sashand respectively engage beads formed on plates 29, in turn held by thecleats 12. FigaS shows a tongue-and-groove connection between the parts12 and 18 at each side of the latter.

IOO

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of a sash, a cleat, a platecarried on the cleat and having overhan ging edges, a plate carried onthe sash and having inturned edges to slidably engage the overhangingedges of the iirst-named plate, a casing carried by the window-sash, atumbler having hollow trunnions mounted in the cas` ing and projectingto the outer face of the window-sash, and a bolt slidable in the casingand actuated by the tumbler and capable of removably connecting the sashand cleat with each other.

2. The combination with a window-frame provided with a bead formed witha recess near its top, of a cleat slidable on said frame and providedwith a spring-controlled camshaped bolt arranged to enter the saidrecess and by which said cleat is rigidly connected with said bead atthe upward limit of its movement, a sash mounted to slide on said cleatand detachable therefrom, and means for rigidly connecting said sash andcleat.

3. The combination with the window-frame, and the bead provided with arecess near its upper end, of the cleat slidable upon said frame, a sashslidable upon said cleat, a spring-controlled cam-shaped bolt carried bysaid cleat and arranged to enter the recess in said bead when the cleatis at the upward limit of its movement, a casing carried bythewindow-sash, a tumbler having hollow trunnions mounted in the easing andprojecting to the outer face of the window-sash, and a bolt slidable insaid casing being actuated by said tumbler, and by which the sash isrigidly connected with the cleat.

4. The combination with the window-f ram e, of the cleat slidablethereon, means for rigidly connecting said cleat with the frame when theformeris at the upward limit of its movement, a sash fitted to slidelongitudinally on and oi said cleat, said cleat and sash havinginterlocking edges by which they are held against lateral displacement,and means for rigidly connecting said cleat and sash together.

5. The combination, with the windowframe, of a sash, a cleat slidablethereon, a plate carried by said cleat, and having overhanging edges, aplate carried by said sash and having inturned edges arranged to engagethe overhan ging edges of the first-named plate and by which said cleatand sash are slidably connected, a spring-actuated device carried bysaid cleat and arranged to antomatically engage the window-frame,whereby to rigidly connect said cleat therewith, and means for rigidlyconnecting said cleat and sash.

6. The combination with a window-frame provided with a recess near itstop, of a cleat slidable on said frame and provided with aspring-controlled cam-shaped bolt arranged to enter said recess and bywhich said cleat is rigidly connected with the frame, a plate carried onsaid cleat and formed with overhanging edges, a sash provided with aplate formed with inturned edges arranged to engage the overhangingedges of the iirst-named plate, and by which said sash and cleat areslidable one upon the other, and means for rigidly connecting said sashand cleat.

7. The combination with the window-frame provided with a bead -formedwith a recess near its top, of a cleat slidable on said frame andprovided with a spring-controlled camshaped bolt arranged to enter saidrecess and by which said cleat is rigidly connected with said bead atthe upward limit of its movement, a sash slidable longitudinally on andoit said cleat and being held from lateral displacement by its edgesinterlocking with the edges of said cleat, and means for rigidlyconnecting said sash and cleat.
